There’s gold in them thar telecommunications networks, and Guavus wants to help carriers find it. On Thursday, the San Mateo, Calif.-based big data company said it raised another $9 million in funding — from new investors Goldman Sachs and TransLink Capital — bringing the company’s total investment to $87 million and helping to finance acquisitions and a global expansion into Asia.

In a nutshell, Guavus is trying to make telcos — including “all tier-1 mobile operators” — smarter by letting them make sense of the data their networks are generating. Those companies are historically alright at using their demographic and billing data to improve marketing efforts, but they’ve been largely blind to what’s happening on their networks, Guavus Founder and CEO Anukool Lakhina told me during an interview a few months ago. However, he said: “The magic happens in marrying and infusing that network data with the demographic and billing data.”

Guavus has actually been busy lately. In January, it closed a $30 million funding round and bought mobile-analytics startup Neuralitic Systems less than two weeks later. When I spoke to Lakhina about that acquisition, he said the plan is to use Neuralitic’s marketing and application expertise to help customers automate business processes, promotions and other functions based on their newfound insights into what’s happening across the entire company.
